Explanation
Correct answer: C) Drum
Vertical lines on a laser printer printout are often caused by a problem with the drum. The drum is a crucial component in a laser printer that transfers the toner onto the paper. If the drum is damaged or worn out, it can result in imperfections such as vertical lines on the printed page.
Explanation of other options:
-
Mirror: The mirror reflects the laser beam in the printing process, but it would more likely cause blurry or incomplete images, not vertical lines.
-
Fuser: The fuser melts the toner onto the paper. If the fuser were malfunctioning, it could cause smudging or incomplete toner adhesion, but not specifically vertical lines.
-
Toner: While low or faulty toner could cause streaks or faded areas, vertical lines are usually related to the drum rather than the toner itself.
